Just more speculation, but I could see that having grown up near there, Rutgers may have always been his favorite school and he only went to PSU because of the wrestling opportunities. Therefore, if desiring to go closer to home, it could be that Rutgers is now by far the place he would want to be….if its possible. Again, just throwing out possibilities if this is a real issue.
I know for my son, once he decided he wasn’t going to play baseball in college (he had offers at smaller schools), PSU was the only place he wanted to be, but it was not a baseball option for him, so he considered other schools up till that decision. Maybe something similar for Nick. Hope it works out for him either way. You only get to do this once.
I would also say that I don't think it would be an issue going back after this. My son is a senior, and from observing, the kids all know how hard things are and seem to understand these types of struggles and quickly forget and put it in the past a lot better than adults seem to.
